T u wit/0m' t'mafl/con/CWW/f N theiisual die or embossing roller of the ina- Be it known that I, LLEWELLYN P.' DAVIS, chiue, and E a piece of molding being carried of Chicagdin the county of Cook and State vby the work support and acted upon by the of Illinois, haveinvented Certain new and useroller D. The die D may be understood as 55 ful Improvements 'in Adjustable Work-Supbeing held byan arm arranged above the bed ports; and I do-hereby declare that the folvor supporting table B and the material as belowing is a full, clear, and exact description 'Ting carried over the table beneath said die thereof, reference being had to the accompaby means of a driven bed roll in the usual nying drawings, and to the letters of refermanner. lo ence marked thereon, which form a part oft y The Work support A is composed of two this specification. principal parts A' and A2, the lower portion The object of this invention is to provide `A having a liat under surface and straight an improved construction in work-supporting parallel sides. In practice it will usually be devices to be employed in connection with .made in sections or lengths of about three feet 65 wood embossingor decorating machines, such -orv of other length convenient for handling. as are used for ornamenting wood moldings The upper surface of the lower portion A is and the like. -The invention consists essen- `provided with a longitu-dinal cavity d, the snrtially in a traveling work support, adapted face of which is a part of a cylinder, and to to be adj usted in such manner as to bring an this is accurately fitted the lower surface of 7o zo inclined surface of the molding or other strip ,the superposed part A2. The upper surface to be decorated into a horizontal position to 0f the part A2 is composed of three surfaces meet the working face of the die or embosswhichin thisinstance are p1anes,twoof which. ing roller, which latter, in connection with -to wit: a and a2,are parallel and the third, my improvement, always preserves a horio2, intersects them to form a shoulder against 75 zontal axis of rotation. Heretofore machines Awhich one edge of the molding strip E may of this character have been adapted to probear while its bottom rests upon the lower duce the same general result by adjustment surface a. The surfaces a and a2 are desirof the die or embossing roller to the required ably protected by a sheet metal facing, as inangle, but such construction has many and dicated in Fig. 2. Obviously the upper part 8o 3o serious objections, all of which are obviated A2, having its lower surface convex, may be by my present improvement. rotated in the cavity a of the lower part A' The nature of the invention will be underso as to bring the upper inclined surface of stood from the following description of the a molding placed upon the part A2 into a horiaccompanying drawings, in whichzontal position so that said upper surface may 8 5 3 5 Figure l is a side elevation of parts of two fairly meet the peripheral surface of the emadjacent sections of the work support embossing die or roller D, as indicated in Fig. bodying my invention. Fig. 2 isatransverse 2, and this will be true no matter what the vertical section taken on line 2 2 of Fig. l, inclination of the upper surface of said moldshowing the arrangement of the clamp which ing may be to the lower surface which rests 9o 4o holds the parts of a section in adjusted relaupon the support.

Fig. of the work-support at any angle or other 3 is a plan view of the lower part or shoe of position to which said upper part may be 9 5 a section and the part of the clamping mechbrought. Such means, as shown in the drawanism carried thereby, the upper part of the ings, consist of a clamping bolt G having a support being removed. head g upon its lower end and a nut g upon As shown in' said drawings, A designates its upper end; said bolt passing through the the traveling work support as a whole; B, the upper part A2 of the work support. The'head rc o 5o main table of the machine; C, the bed roll g of said clamping bolt engages beneath upon which the work support is carried; D, anges f2 of a T-groove F formed in a curved metal block F which is secured transversely to the part A. Preferably said T-grooved metal block F has its margins f Hush with the concave surface a of said part A of the support, and has a central elevated portion j" containing the T-groove F', which elevated partf ts a tranverse groove a4 in the lower convex surface of the upper part A2. As shown, the head g of the clamping bolt G is cut away on its sides to conform to the lower convex surfaces of said flanges f2 which border the T-groove F so that said head bears broadly against said surfaces and is adapted to hold firmly without slipping. It will be observed that the clam ping bolt G is arranged to protrude through the more elevated surface a2 of the upper part A of the support where it is at all times accessible and permits of the clamp being tightened after the adjustment has been effected beneath the pressure of the roller die D.

Other forms of means for clamping the parts or for holding them in the selected relation may be adopted in place of the clamping bolt and T-grooved part F herein shown without departure from my invention.

The upper part A2 of the work support will ordinarily be of the same length as the lower part A', but desirably said upper part will be placed so as to overhang the lower part at one end and to leave the lower part projecting` beyond the upper part a corresponding distance at the other end. By this construction two supports, when placed end to end, will overlap, as indicated in Fig. l. and they will better support the work beneath the pressure of the roller die as the joint between two sections passes over the subjacent bed roller C.

I claim as my invention- 1. An adjustable, traveling work support comprising a base member for engagement with the feed roller of a wood decorating machine or the like, a work supporting mem'ber resting upon said base member and adapted for angular adjustment with relation to the latter, and securingr devices for retaining said member in adjusted relation, substantial] y as set forth.

2. An adjustable, traveling work support comprising a base member for engagement with the feed roller of awood decorating machine or the like,aworkr supporting member superimposed upon said base member, the meeting faces of said members being respectively concave and convex in cross section, and devices for securing said members together in adjusted angular relation,substan tially as set forth.

3. A system of traveling work supports for wood decorating machines, comprising a se ries of sections or lengths each composed of a lower part and an upper part, the latter of which has its upper surface adjustable to any desired angle, as set forth, the upper and lower parts being of equal length but placed in overhanging relation to eachother, whereby the several sections of the system will overlap each other when placed end. t0 end in the machine, substantially as described.

4. In combination with the lower part A of the traveling work support having its upper surface concave in cross-section and provided with a curved metal part F having a T-groove therein extending transversely of the support, the upper part Azof the support having a lower surface fitted to the concaved upper surface of said lower part A and provided with a clamping bolt G engaged with the said T-groove, substantially as described.

In testimony that I claim the foregoing as my invention I aiix my signature in presence Vof two witnesses.
